During one last fly-in fishing trip to Canada with Marshall and their fathers, Ethan risks his life to save his friend as tragedy ends the outing. Ethan becomes a bomb-dog handler in the Marine Corp, and when the unthinkable happens in Afghanistan, it's up to Marshall to make sure that Ethan doesn't give up on the difficult journey back to health. He knows that a true friend should always be there.
